HEATER.

I to be heated will be reduced to a minimum.

A further object is to so construct the heater as to improve the circulation and consequently the heating capacity.

Another object is'to provide for a free flow of water from and to the heater.

An object also is to provide a larger space in the fire pot and throughout the heater for burning the gases and thereby avoid the wasting of the calorific values in the gases.

A still further object is to so construct the sections of the heater that a small fire may be utilized economically by acting on part of the sections and the water therein.

To effect these objects I have constructed and arranged my invention as hereinafter more particularly explained.

Figure 1, is a sectional elevation of my improved heater. Fig. 2, is a perspective View of the main fire-box port-ions of the heater. Fig. 3, is a detail of one of the sections of the main fire-box portions. Fig. 4, is a vertical section showing the communicating passage-way between the fire pot ring section and the upper sections of the main fire-box portions. Fig. 5 is a horizontal cross-section through the vertical portions of the fire box sections, and Fig. 6 is a cross section through the ring section showing the major portion of the heater in plan.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the fire pot water section, which is provided with a return branch A forming part of the same.

B are a series of sections, which together make up the main fire-box portions B. Each section B comprises three legs 13 B and B, which taper toward the top, being bent inwardly as indicated to an apex B which is formed with a hollow boss B horizontally disposed.

B is a hollow base, which extends below the lower vertical portion of the legs. The base B is provided with recessed outer portions 13 through which extend bolt holes 13.

2 are openings, which extend and register with smaller openings 3 made in the top of the fire pot water section.

The fire pot water section A is provided with recesses A and bolts 4, which extend through the holes B into the recesses A and thus secure the fire-box portions B in position.

As will be seen the sections besides each converging at the top all combined converge at the top toward a water section C, which is formed at the bottom with a hollow ring C having peripheral hollow bosses C and vertical pipes C extending upwardly into the chamber C The upper ends of each section B are connected to the section C by the hollow screw plugs D having lateral openings D therein in order to permit of the passage of the water freely therethrough, that is from the top of the sections B int-o the ring C.

E is the lower casing of the heater, which is provided with a suitable fire clay lining E. The upper portion of the casing E converges toward the water section C, so as to leave an opening E around the same.

F is an upper casing, which converges or tapers at the bottom being secured by suitable flanges F to the converging portion of the casing E.

G is the smoke pipe, which is connected to a thimble F on the downwardly converging portion of the upper casing F. The smoke pipe G extends downwardly at an incline and horizontally and upwardly as indicated.

H is a deflecting plate, which is secured in position on a bridge H extending from the casing F to the casing E. The deflecting plate H is designed to prevent the products of combustion from passing through the smoke pipe too directly, and'thus enable me to procure for my furnace the greatest amount of value from the products of combustion.

I and J are the inner and outer ring sections each of which comprises the vertical legs I and J, respectively, which are connected together by communicating passageways I and J respectively.

K is a double elbow, which has connecting flanges K by which it is secured to the flanges I and J formed at the bottom of the sections I and J. The outer end of the elbow extends through the casing F and is provided with a flange K by which it is connected to the down pipe L, which is connect ed at the bottom by a flange L to the flanged hollow boss L communicating with the return branch A.

Preferably dian'ietrically opposite to the hollow boss flanges l3 and J are located at the upper end of the sections 1 andv J the hollow boss flanges li and J". The upper end of the water section ti -is also provided with llangcs M is the head, which is connected by the llangcs or the hollow bosses ill. M and M" to the l'langes C of the hot water section 0 and the flanges of the hollow bosses l" and il Having now described the principal parts involved in my invention I shall brietly de scribe the utility or my heater.

The products of combustion within the fire pot section Jr and the hottest gases pass upwardly within the main fire-box portions or circulating section B atlecting all the pipes and as there is a maximum surface exposed producing the heat in the fire-box portions very rapidly. The products of com bustion pass upwardly within the section C and outwardly through the opening E as well as through the openings between the legs C The products of combustion also pass upwardly around between the ring sections 1 and J, which are corrugated or more properly formed with. separate legs as hereinloetore described in order to give a maximum surface to be acted upon by the products of combustion. The products of combustion it will thus be seen have practically all their calorific value extracted from them before they pass downwardly into the smoke pipe ll hen there is a small fire, the water, or steam it it be a steam boiler, may be heated only in the main sections A B and C and yet the circulation Of the water will be assured as itwould pass outwardly and iu'nvardly through the chzunber G and head M and return through the branch ll hen a greater heat is required the products of combustion of a much larger fire, which would then be necessary will affect the ring sections l and J to a greater extent and the heated water from them will pass outwardly through the head M and return through the branch it. The pipe L communicating with the sections will serve to keep the circulation even throughout the heater. The sections l and J are practically constructed very much the same as a circular fire-box portion with. openings between all the legs, whereby the products of combus tion may pass therein. Again on account of the unitary castings B it will be seen that I am enabled to use such castings for ditlerentdiameters of heaters and thereby save material in the cost of patterns as such unitary castings can be utilized for practically all sizes of boilers it is necessary to make. Besides being thus standard in case of rearia pairs these can be readily efiected. Again the ring sections I and J may be adapted for different sizes of boilers as, of course, in small boilers only one ring would be need ed while in large boilers two or more rings would be necessary the size depending upon the diameter oi? the boiler. The inner section C may be also used for dillerent sizes of boilers as the bosses formed on the ring 0 would be made se iarately and longer or shorter bosses utilized in accordance with the diameter required. it will thus be understood that a number of sized boilers can be made at but a minimum expense particularly as to patterns. The fitting is also reduced to a minimum.

Although I have described my invention particularly as to hot water heaters it will, of course, be understood that a dome may be readily superimposed upon the hot water section C and the head otherwise constructed for steam boilers as may be found most conducive to the proper development of my invention.
